The back edge of some steadier and heavier rainfall is now working its way through the I-95 corridor, but that does not mean this precipitation event is ending. A surface cold frontal system still resides to our west and there will be some light precipitation later today and tonight that will likely ultimately change from plain rain to ice and/or snow in many areas as colder air filters in from the northwest. The combination of light frozen precipitation and rapidly dropping temperatures late tonight could very well create slippery “black ice” conditions in the I-95 corridor that last into tomorrow morning. The frozen precipitation amounts in the overnight hours will likely be on the light side, but it doesn’t take much to cause problems on the roadways; especially, when combined with quickly dropping temperatures as yet another very cold air mass moves into the region. This very cold air mass will be anchored by strong Arctic high pressure on Tuesday edging eastward from the Northern Plains. Temperatures tomorrow afternoon will struggle to pass the 30 degree mark in many I-95 corridor locations and the teens are likely to be quite widespread tomorrow night. Watch for slippery spots later tonight into early Tuesday.
